(54) ДИАФРАГМРННЫЙ НАССЮ(54) DIAPHRAGM NASS

1one

Изобротенио относитс к насicocrpoeнию , касаетс диафрагменных насосов и может найти применение в различных отрасл х народного хоз йства дл перекачки текучих сред.Inobrotenio relates to nasicocompatibility, refers to diaphragm pumps, and can be used in various industries of the national economy for pumping fluids.

Известен диа(})рагменный насос, содер- жаишй р д последовательно установленных в рабочей полости биморфных диа45 агм, закрепленных по периферии в корпуса и снабженных в центральной части обратными клапанами, ориентированными в одну и ту же дл всех диа4рагм сторону i .A diagonal pump is known; it contains a series of bimorph diam argues sequentially installed in the working cavity, fixed peripherally to the housing and fitted in the central part with check valves oriented in the same direction for all diagrams i.

Недостаток этого насоса - при прогибе диафрагмы наибольшее перемыл аше имеет |, центральна часть, а к периферии перемещение падает. Поэтому, измещенный диафрагмой объем существенно меньше, чем измещенный объем ис щневого насоса при ходе порщн равном максимальному о прогибу диафрагмы, и равном с ней диаметре . В силу отмеченных обсто тельств, удельные показатели насоса, также как напор, объемна посто5а1на , удельна The disadvantage of this pump is that during the deflection of the diaphragm, the largest washed up has |, the central part, and to the periphery the displacement falls. Therefore, the volume displaced by the diaphragm is significantly smaller than the displaced volume of the artificial pump with a stroke equal to the maximum deflection of the diaphragm and the diameter equal to it. By virtue of the noted circumstances, the specific indicators of the pump, as well as the pressure, are constant in volume, specific

мощность и другие, оказываютс заниженными .power and others are being understated.

Цель изобретени - повыщение показателей насоса. Дл этого кажда диафрагма снабжена жесткими дисками, закрепленными в центральной части на диафрагме.The purpose of the invention is to increase pump performance. For this, each diaphragm is provided with hard disks fixed in the central part to the diaphragm.

На чертеже изображен предлагаемый насос.The drawing shows the proposed pump.

Claims

The pump contains a series of consecutively mounted in the working cavity 1 of bimorph diaphragm 2, closed around the periphery in the housing 3. In the central part of the dia (agms 2 are equipped with check valves made in the form of conical nozzles 4. In the housing 3 along the ends are also conical nozzles 5 . All check valves — conical nozzles 4 and 5 — are oriented in the same direction for all 2 sides .. Each diaphragm 2 is equipped with a hard disk 6 fixed in the central part of diaphragm 2 on a conical nozzle 4. Between each disk 6 into the bottom my 2 educating and cavity 7 communicated through the gap between housing 3 and disk 6 with a corresponding working chamber 8 formed by diaphragms 2 in working cavity 1. Each bimorph diaphragm 2 is formed by two flat piezocrystals connected to each other and connected to a power source (not shown in the drawing) in antiphase. When applying high frequency voltage to a bimorphic diaphragm 2 from a phase-shifted power source, phase-shifting diaphragms 2 are produced. The oscillations of each diaphragm 2 are affected by that. that the piezocrystals are fed in the opposite phase and the compression of one of them occurs simultaneously with the expansion of the other. At the same time, the diaphragm 2 is bent towards the stretching piezocrystal. The disks 6 associated with diagrams 2 in the central part oscillate with an amplitude equal to the amplitude of the oscillation of the central part of the diaphragm.

2. Conical nozzles 4 and 5 have the best conductivity of the pumped medium in the direction of constriction and act as check valves, providing movement of the pumped fluid in one direction during reciprocating movements of the discs 6. Due to inertia during high-frequency oscillations of the disks 6, the pumped medium is not manages to flow from working chambers 8 into space 7 between diaphragm 2 and disk MI 6. At the same time, vapor – gas interlayers that do not prevent the movement of disks 6 are located in cavity 7, because disks 6 having an area close to th to the area of the diaphragm 2 oscillate over the entire surface with uniform amplitude equal to the maximum amplitude of oscillation of the diaphragm 2 in its central portion, it increases the pressure, volumetric constant, power density, and other parameters of the pump unit. Claims of Invention A diaphragm pump comprising a series of bimorphic diameters set in the working cavity is fixed: x along the periphery in the housing and fitted in the central part with check valves oriented in the same direction for all diaphragms, which differs in Increasing specific values, each diaphragm is fitted with a hard disk mounted in the central part on the diaphragm.
